Seashore Charter Schools

The Seashore Charter Schools district in Corpus Christi, Texas, serves 405 students across two schools: Seashore Learning Center (grades K-4) and Seashore Middle Academy (grades 5-8), earning a strong 4-star rating and ranking in the 82nd percentile statewide.

Seashore Middle Academy is the district's standout but most volatile school. It achieved a perfect 100% proficiency in Algebra I in 2024-2025—53 points above the state average—and posted exceptional 78% proficiency in 8th Grade Science. However, this same school saw a dramatic 38-point drop in Algebra I the following year and a puzzling 63-point gap between its 5th Grade Science (14.6%) and 8th Grade Science (78%) scores in the same year. Its ranking has declined from the 89th to the 69th percentile over three years. In contrast, Seashore Learning Center offers steady, above-average performance, particularly in 4th Grade Math, which consistently outperforms the state by over 20 points. Its ranking has remained stable in the 74th-82nd percentile range.

Both schools benefit from small class sizes, with student-teacher ratios of 13.5:1 at the Learning Center and 11.9:1 at the Middle Academy. The Middle Academy spends $8,010 per student—$290 more than the elementary school—yet its performance is more erratic, suggesting curriculum quality matters more than spending alone. With only 167 middle school students, a single cohort can dramatically swing results, as seen in the 100% Algebra I score likely from a small group of high achievers. The district's 0% dropout rate at the Middle Academy is excellent, but the missing free/reduced lunch data limits a full understanding of socioeconomic factors. Overall, families should expect strong elementary math instruction but prepare for significant year-to-year performance swings at the middle school level.
